WRENCH.

SPECIFICATION forming part of Letters Patent No. 603,178, dated April 26, 1898.

Application led J' uly 26, 1897. Serial No. 645,921. (No model.)

To @ZZ whom it magma/cern:

Be it known that I, MERRITT H. OURRY, of

North Pomona, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Wrenches; and I do hereby declare the following to be a full, clear, and exact description of the invention, ysuch as will enable others skilled in the art to which it appertains to make and use the same.

' My invention relates to new and useful improvements in wrenches especially designed for use in connection with the putting on and taking off of vehicle-wheels.

The object of the invention is to provide a device of the character above mentioned that will be simple in construction, economical, durable, and efficient in operation.

A further Object of the invention is to produce a wrench that will be adapted to grip the rim of the hub and the bolt at the same time, the wheel of said vehicle being turned to remove the nut.

I am enabled to accomplish the objects of the invention by the simple means illustrated 'in the accompanying drawings, in which- Figure l is a perspective|view of the wrench; and Fig. 2 is a central longitudinal section of the same, showing the same in position for taking off'a nut.

Referring to the drawings, the numeral 1 indicatesthe body of the wrench, which is constructed of any suitable material, round in cross-section at its forward end, as indicated by the numeral 2, and provided with a square recess 3. The said body is slotted longitudinally at the top and bottom thereof,

as indicated by the numeral 4, and said slots have pivoted therein two levers or handles 5, which may be of any suitable length, and said levers are provided at their forward ends with notched or roughened portions 6, adapted to engage the inner periphery of the rim of the hub when the wrench is in position for use. Secured to yone of the levers is ametallic plate 7, provided with an elongated slot 8, through which passes a screw-threaded bolt 9, which is rigidly secured to one of the levers, and said bolt is provided with a turn-button l0, which is adapted to be secured upon said plate at any desired point thereof to lock the forward ends of the levers in contact with the inner periphery of the rim of the hub.

In operation the forward ends of the levers are compressed until their upper surfaces are approximately flush with the circumference of the forward end of the body. The wrench is then put upon the nut. The rear ends of the levers are then pressed together, forcing the rou ghened surfaces upon the forward end of said levers in close contact with theinner periphery of, the wheel. When this done,the turn-button is tightened, locking said levers in contact with the hub-rim.

It is apparent that all that will be necessary to remove the nut after the wrench is locked in the position described is to turn the vehicle-wheel.

It will be understood that the shape of the recess in the wrench-body may be varied and adapted to it hexagonal or other forms of nut.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A wheel-nut wrench, comprising a body having its forward end recessed for the reception of a nut and provided with longitudinal grooves, vand levers fulcrumed to said body and adapted to fit within said grooves so that their outer surfaces may lie flush with the outer surface of said body, as and for the purpose set forth.

2. A wheel-nut wrench,'comprisng a bod having its forward end recessed for the recep tion of a nut and provided with longitudinal grooves, levers fulcrumed to said body and adapted to fit within said grooves, so that their `outer surfaces may lie flush with the outer surface of the body, and means for locking said levers, one to the other.

3. A wrench of the character described comprising a suitable body having a recess in the l end thereof adapted to t over the nut, and

having longitudinal grooves therein, levers pivotedin said grooves, and provided at their forward ends upon the upper sides thereof with roughened surfaces adapted Vto engage the inner periphery of the rim of the hub when the levers are compressed, a plate secured to one lever and provided with a slot, a screw-threaded pin on the other lever adapted to pass through said slot, and a turn-button ICO upon said pin adapted to be brought in close contact with said plate to lool; the levers in contact with the hub-rim, substantially as and for the purpose set forth.

4. A wrench of the character described coinprisin g a suitable body provided in its forward end with a recess adapted to engage the nut, said body being provided with longitudinal grooves opening into said recess, levers pivoted in said grooves, and provided at their forward ends with roughened surfaces adapted to engage the periphery of the hub-rim, a slotted plate secured to one lever, an exteteriorly-screw-threaded pin secured to the other lever and passing through the slotted plate, said plate bein g provided with a rough- MERRITT H.
